Otherwise the Cosserat rod code will not compile without dune-parmg.

This class will gradually replace the current implementations
GlobalP1Mapper and GlobalP2Mapper, because dune-gfe is not
the proper place for infrastructure for distributed computing.
Plus, the stuff in dune-parmg already is more flexible and
powerful.

Using LocalIndexSet objects was mandatory with dune-functions-2.5
and earlier.  However, we only support 2.6 and later anyway,
so let's get rid of the backward-compatibility code.

The current implementation assign one degree of freedom to each
element, regardless of its type.  That only works for quad grids:
We are implementing Lagrange FE here, and these don't assign
degrees of freedom to triangles.

It is not actually used.

... while keeping compatible with dune 2.3

In particular this means having to carry mappers for the local indices around.
This makes the code more verbose, but it also makes it easier to see what is
happening.  While coding this stuff I keep having doubts about whether all
the renumbering works correctly...

The local copy was to get the thing developed and working.  Now that it is
working we upstream it into dune-grid.

The IndexSet interface class from dune-grid doesn't have it, and we want
to be like the interface method as much as possible.

[[Imported from SVN: r9921]]

That's what this method is called in the dune-grid IndexSet
interface.
